I'm looking for a noun that describes a car passing through a tollgate; it's this event I'm trying to name. A person going through a turnpike might be similar, I guess. Possible use of word would be for example:
- 500 cars passed through this tollgate today.
- There were 500 "x"s today from this tollgate.
- There were 500 car "x"s today from this tollgate.
Passage was the first word I thought of, but google doesn't seem to agree (I'm still not sure though).
Clarification: It doesn't have to be a tollgate (which guards the boundaries of a highway). Let's say, for example, a person is standing next to a road and counting the number of cars that pass. At the end of the day, he says "500 cars passed today; there were 500 x's".
